JOSEPH JAGGER, OF GLENHAM, NEW YORK.

L0 0 M I SPECIFICATION forming part of Letters Patent No. 403,194, dated May 14, 1889.

Application filed March 31, 1886. $erial No. 197,315. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH JAGGER, of .Glenham, in the county of Dutchess and State of New York, have invented a new and Improved Loom, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved loom for weaving Brussels velours.

The invention consists of a section-wheel operated and locked from the main shaft and connected with cams and levers operating the healds, the jacquard, and the picking devices, and of a device for insuring regular measurement of each pattern woven.

The invention also consists of various parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a broken side elevation of a loom, showing my improvement. Fig. 2 is a plan view of the same, partly broken away. Fig. 3 is a face view of a section-wheel. Fig. at is a sectional elevation of the same. Fig. 5 is a face view of asection-wheel having twelve divisions. Fig. 6 is a sectional elevation of Fig. 7 is a face view of the two fine chain-cams. Fig. 8 is a face view of the picking-cam. Fig. 9 is a face View of the comber-board cam. Fig. 10 is afaoe view of the driving and locking wheel for the sectionwheel. Fig. 11 is an edge view of the same, and Fig. 12 is a side View of the healds and their operating mechanism.

The frame A of the loom is provided with a crank-shaft, B, which operates the lay and other parts of the loom in the usual manner.

' On one end of the shaft B is attached a driving and locking wheel, 0, provided with the projecting pin 0 and having an annular raised proj ection, G On the shaft D, having its bearings on a frame, A, secured at one side of the main frame A, is mounted the section-wheel E, having eight twelve, or more slots or recesses, E, in its rim, and having the curved parts E between the recesses E, as shown in Figs. 3 and 5. The section-wheel E is provided. with a hub, E on which are mounted the fine chain-cams F and F ,which are fastened to the section-wheel E by the bolts E projecting from the section-wheel E and passing through suitable apertures in the fine chain-cams F and F.

The fine chain-cams F and F are each provided with a cam-groove, F in which is placed a friction-roller, G mounted on a stud attached to the lever G or G, said levers being fulcrumed at one end on a shaft, H, mounted in suitable bearings attached to the main frame A and to the frame A. The other ends of the levers G and G are connected to the healds I I by means of the levers g g, connecting-rods 9 links g and hooks g 9 as shown clearly in Fig. 12.

On the hub E of the section-wheel E are also placed the working-cams J J, also fastened to the section-wheel E by the bolts E, which are passed through the working-cams. Each of the working-cams J J is provided with a cam-groove, J (shown in Fig. 8,) in which is placed a friction-roller, K mounted on a stud attached to the levers K and K, re-

spectively, one end of each of said levers being fulcrumed on the shaft H. The other end of the lever K is connected, by the link L, with an arm, L, secured to a shaft, L mounted in suitable bearings on the frames A and A, and the other end of the lever K is connected, by the link M, with an arm, M, attached to a sleeve, M fitted on the shaft L On the shaft D is placed a cam, N, the periphery of which is in contact with a frictionwheel, N, mounted on a stud attached to a lever, N one end of which is fulcrumed on the shaft H, while the other end is connected with and operates the jacquard, which produces the pattern or design, in the usual manner.

The shaft L is provided with an upright arm, L operating the horizontal oscillating picking-shaft 0 on the left side of the frame A, and the sleeve M is provided with an upright arm, M operating the horizontal oscil-' lating picking-shaft P on the right of the frame A. The picking-shafts O and P are operated by the action of the revolving comberboard cams Q, secured to the shaft D, and provided with one, two, three, or more picking-cams, Q, and the cams Q. operate the levers R in the usual manner for working the Jacquard harness comber-board.

The spike or breastroller S, which draws forward the carpet as it is woven, is operated by a worm and w0rin-wheel from the shaft 1) by the inclined shaft S, provided with the clutch S and the clutch-lever S, for stopping the rotation. of the shaft S for letting back the cloth. The shaft S is provided on its upper end with a worm, i, which is in gear with the worm-wheel S attached to the shaft S, on which the breast-roller S is mounted. To the shaft S is attached, by means of a setscrew, the roller T, having on its periphery small projecting pegs T.

On the cross-bar A" of the main frame A is attached the guide-plate U, and over it and the roller T passes an endless belt, V, which also passes under a tension-roller, V, mounted in a suitable bearing attached to the floor. The belt V is provided with a number of apertures corresponding to the pegs 'l" on the roller T.

The operation is as follows: Each revolution of the crank-shaft B rotates the wheel once, so that the pin. 0, projecting into the top recess, E, of the section-wheel E, turns the latter in the direction of the arrow at the distance of the division of the section-wheel usedthat is, an eighth or a twelfth part of the periphery of the said wheel E. As soon as the pin 0 leaves the recess E the sectionwheel remains stationary until the pin C comes in contact with the next recess E of the section-wheel E, and the latter is held in a locked position during the stationary period by the annular projection C beingin close contact with the curved part E of the section-whcel. This partial rotation of the section-wheel E is imparted to the fine chaincains F and F and to the working-cams J and J. As the two fine chain-cams F and F are placed in opposite positions to each other, as shown in Fig. 7, they operate the healds I and I alternately, and as the two working-cams J and J are also placed in opposite positions to each other they alternately operate the pickingshafts O and P. As the main crankshaft B rotates eight or twelve times before imparting a full revolution to the sectionwheel and the cams attached to it, it will be seen that the healds and the picking-shafts are operated correspondingly through the respective levers G G and. K. K, provided with the friction-rollers K and G which engage with the respective canrgrooves and the several connections with the healds and the picking-shafts above described. The picking-shafts O and P are alternately placed in position for picking by the arm L, attached to the shaft L and the arm M, attached to the sleeve M \Vhen a section-wheel, E, having twelve divisions or slots, E, in its rim, as shown in Figs. 1 and 5, is employed, then the picking is accomplished by, first, left, right, left, then miss or stand for three revolutions of the crank-shaft, making six revolutions of the crank-shaft, and then repeat, picking right, left, right, and miss or stand again during three revolutions of the crank-shaft, making again six revolutions of the crankshaft, thus making twelve revolutions of the crank-shaft to one revolution ofthe said section-wheel.

The shuttle ceases to operate whenever the rollers K of the working-cams J J are on a level, as the said rollers K then travel on the depressed circular part of the groove of the cams J J, and the levers K h", operated by the said rollers K remain inactive. The levers K K are again raised and lowered alternately, when the said rollers 1' travel over the irregular parts of the grooves of the cams J J. As shown in Fig. 8, the rollers are one above the other and the shuttle is operating.

At the stopping of the shuttle the pile wire for the loop is drawn out of the cloth and placed under the warp raised by the jacquard. Now, when a section-wheel, E, having eight divisions or slots, E, in its rim, as shown in. Fig. 3, is employed, then the picking is aceomplished by first left, right, left, miss or stand for one revolution of the crankshaft, making four revolutions of the crankshaft and one half-revolution of the section-wheel, and then right, left, right, miss or stand for one revolution of the crankshaft, making again four revolutions of the crank-shaft and one half revolution of the section wheel. Thus the crank-shaft makes eight revolutions to one full revolution of the section-wheel, having eight slots, E.

The revolving of the shaft 1) imparts a rotary motion to the spike or breastn'oller S by means of the shaft S and worm S and the worm-wheel 5, attached to the shaft S, and as the roller T is attached to the latter the belt V travels with the same speed as the woven fabric which passes over the roller S.

The object of the belt V is to insure regular measurement of each pattern woven, and if the latter is, for instance, sixty inches long the belt is to made of the same length. The belt V does not change its relative length. by traveling around the roller T and the frictionroller \V, being propelled by the pegs T engaging with the eorresponding apertures in the belt; but the worsted or woolen printed warp docs vary its length as the fabric is woven, and has to be regulated by the deadweight on the tension device usually e1nployed on the warp.

The dezutweight on the tension device is increased or diminished according to the variation in the length of the patterns in the warp as the weaving progresses. If this variation in the length of the pattern in the warp were not regulated, then the weft would not be united with the warp at the proper point, and the pattern of the finished carpet would be distorted.

By increasing or diminishing the deadweight on the tension device while the weav-= 403,194 r p a ing is progressing the Warp is stretched or relaxed, so that the Weft enters at the proper point, thus forming the correct and uniform pattern on the finished carpet. Now, it is evident that as the fabric and the belt V travel together the Variation in the length of the pattern of the fabric can be at once discovered by referring to a starting-mark on the belt, and the weaver can increase or diminish the dead-weight on the tension device, so as to correct the difference of travel of the belt and g the fabric.

Having thus fully described my invention, I claim as new and desire to secure by Let ters Patent- 1. The combination of the crank-shaft B, the driving and locking wheel 0, and the section-wheel E, with the Vfine chain-cams F and F, the levers G and G, provided with the friction-rollers G the healds and intermediate devices between the healds and levers, substantially as shown and described.

2. The combination of the crank-shaft B, the driving and locking wheel 0, and the section-wheel E, with the working-cams J and J, the levers K and K, provided with the friction-rollers K the picking-shafts O and P, and intermediate mechanism between the said shafts and levers, substantially as shown and described. a

3. The combination of the section-wheel E, the driving and locking Wheel C, the crankshaft B, and the working-cams J and J, having cam-grooves J with the shafts O P, the

levers K and K, having the frictionrollers K the connecting-links L and M, the arms L and M, the shaft L having the arm L and the sleeve M having the arm M substantially as herein shown and described.

4. The combination of the working-cams J and J, having cam-grooves J the levers K and K, provided with friction-rollers K the links L and M, and the arms L and M, with the shaft L provided with the arm L", the picking-shaft O, the sleeve M provided with the arm M and the picking-shaft P, substantially as shown and described.
